Description
Technical field
The present invention relates generally to cell mobile communication systems.
Background technology
Usually, cell mobile communication systems is standardized theme, can be with reference to the respective standard of being published by the respective standard tissue to obtain more information.
With reference to figure 1, the general structure of this system of brief overview.This system comprises the mobile communications network that is called public land mobile network (PLMN), and itself and portable terminal (MT) and external network (not specifically illustrating) communicate.
Network itself comprises Radio Access Network (RAN) and core network (CN), and wherein, RAN is mainly used in by the wave point between network and portable terminal transmission and managing radio resources, and CN is mainly used in management and transmits and goes to and from the calling of portable terminal.
Usually, these systems are honeycombs, and for the leading subscriber mobility, the sub-district is grouped together in to be called the lane place (LA) that is used for the circuit-mode business or to be called and is included in the route district (RA) that the lane place is used for the group mode business.
As an example, following description relates to the positional structure corresponding to lane place (below abbreviate LA as), and relates to the mechanism that terminal is selected the sub-district in being in the pattern that is called " free time " pattern the time.
Terminal usually by the position updating process informing network owing to be selected for the variation of any LA that the variation of the sub-district of access network causes.This makes network can at first search for this terminal (this is undertaken by search or " paging " process) in corresponding LA when the incoming call that takes place terminal, controls the right that the user inserts selecteed sub-district before secondly in registering a user to corresponding LA.
In this position updating process, portable terminal sends the message that is called position updating request (LUR) to network.
After especially having verified user's right based on user profiles (profile), network can adopt two kinds of possible modes to respond:
If sure response, then the message that turns back to portable terminal by network is that the position is upgraded and accepted (LUA) message; The user is registered among the new LA then;
If the response of negating, then the message that turns back to portable terminal by network is that refusal (LUR) message is upgraded in the position.
In addition, technical variation makes that it is essential distinguishing different wireless access technologys (RAT).
The example of RAT is global system for mobile communications (GSM), and it uses frequency division multiple access/time division multiple access (FDMA/TDMA) access technology, especially so-called " second " for system in.
Another example of RAT is especially at the Wideband Code Division Multiple Access (WCDMA) (W-CDMA) and the time division CDMA (TD-CDMA) that use in for system such as the what is called " the 3rd " of universal mobile telecommunications system (UMTS).
Nature, other examples of RAT also are fine, for example CDMA 2000, unauthorized mobile access (UMA), WLAN-3GPP or the like.Frequency band also can be diacritic key element, for example GSM 900 or GSM 1800.
In addition, any one system (or operator) can use different RAT (this system can be called " many RAT " system).For example, this is corresponding to the third generation foundation structure of just being introduced existing second generation foundation structure gradually, especially make and from the existing covering that provides by existing second generation foundation structure, benefit the continuity that can possess business such as the business by the common support of two generation systems of phone type business.
In the system of " many RAT " type, various subscription profiles can be provided by operator; Especially, subscription profiles can be to make only to allow to insert one or more specific RAT, and does not allow to insert other RAT.
So, the problem that solve is to allow to support the portable terminal of different RAT (for example GSM and UMTS) only to insert some specific RAT (for example GSM, rather than UMTS).
A solution is to dispose LA (this LA can be known as " single RAT " LA) in the mode that the sub-district in a LA is associated with single RAT, and the register requirement of the terminal among the LA that only acceptance is comfortable with this RAT is associated.
The solution of this single RAT LA type especially has unintentionally, and the free burial ground for the destitute increases the shortcoming that traffic carrying capacity is upgraded in the position, (this may often take place, and is especially more frequent relatively than change LA in single RAT system) is unique essential because position updating process is a portable terminal from the LA that LA moves to another RAT is associated that a RAT is associated the time.
A kind of solution of avoiding this shortcoming is that the mode that the different districts with LA can be associated with different RAT disposes LA.
Yet, use the solution of this many RAT LA type, present normal conditions can not mandate can support the portable terminal of different RAT only to insert some RAT; No matter RAT how, all sub-districts of many RAT LA all are authorized to.In other words, in present normal conditions, access right restriction (especially according to subscription profiles) can not consider on than the low rank of the rank of LA that this especially based on RAT, produces the problem of access right restriction based on some standard.
Summary of the invention
Specific purpose of the present invention is to address these problems comprehensively or partly and/or avoid comprehensively or partly these defectives.Particularly, an object of the present invention is to keep the advantage of many RAT LA solution and avoid its shortcoming.More generally, an object of the present invention is to improve ambulant management in the system that can use different RAT.
